Description
Technical Field
The invention belongs to the technical field of washing, and particularly provides a pulsator washing machine with a self-cleaning device.
Background
In order to facilitate the life of people and effectively improve the life quality of people, more and more types of washing equipment are continuously emerged on the market to help people wash clothes. In recent years, with the increasing number of washing equipment, people have made higher and higher demands on the comprehensive performance of the washing equipment. Taking the cleaning performance of the washing machine as an example, in order to guarantee the washing effect of the existing washing machine to the maximum extent, users often require the washing machine to have a self-cleaning function, so as to effectively guarantee the cleaning degree of the washing machine, and thus effectively avoid the problem that the washing effect of the washing machine is not good due to the fact that the interior of the washing machine is not clean. In order to make the washing machine have a self-cleaning function, the existing washing machine is usually provided with a self-cleaning device between an inner barrel and an outer barrel so as to clean two parts, namely the outer wall of the inner barrel and the inner wall of the outer barrel, which need to be cleaned most; however, for the pulsator washing machine, cleaning is also needed between the bottom of the pulsator and the bottom of the inner tub, and the existing washing machine does not provide any cleaning scheme for the problem.
Further, even if the scheme of cleaning the inner and outer barrels is applied to the cleaning impeller, the existing cleaning scheme still has many problems. The existing part of washing machines realize self-cleaning by arranging a cleaning brush on one of the outer wall of an inner barrel and the inner wall of an outer barrel, but the cleaning mode can only realize self-cleaning on one of the outer wall of the inner barrel and the inner wall of the outer barrel, but cannot realize comprehensive cleaning of the outer wall of the inner barrel and the inner wall of the outer barrel, and the cleaning scheme is applied to the cleaning of the bottom of a wave wheel and the inner wall of the inner barrel, and cannot realize comprehensive cleaning of the two parts simultaneously; meanwhile, the existing washing machine also partially realizes self-cleaning by arranging a plurality of cleaning balls between the outer wall of the inner barrel and the inner wall of the outer barrel, the cleaning mode seems to realize comprehensive self-cleaning on the surface, but when the inner barrel rotates, the cleaning balls are always gathered at the upper part of the washing machine under the action of buoyancy, so that the cleaning mode cannot realize comprehensive self-cleaning at all, and when the inner barrel does not rotate, the cleaning balls can be gathered near the driving shaft of the washing machine, on the contrary, dirt is easily gathered near the driving shaft, and the cleaning scheme is applied to the cleaning of the bottom of the impeller and the inner wall of the inner barrel, and the same principle cannot well realize the effect of comprehensive self-cleaning. Therefore, the self-cleaning scheme of the existing washing machine can not only not clean the bottom of the impeller, but also is difficult to realize the comprehensive self-cleaning effect.
Accordingly, there is a need in the art for a new pulsator washing machine having a self-cleaning apparatus to solve the above problems.

With continuing reference to fig. 1 to 3, in the preferred embodiment, the self-cleaning device of the pulsator washing machine further includes a centrifugal storage assembly 22 connected to the cleaning chain 20, the centrifugal storage assembly 22 is configured such that when the driving shaft 15 rotates at a high speed, the centrifugal storage assembly 22 can pull the cleaning chain 20 tight to remove the cleaning chain 20 from contact with the bottom of the inner tub 13. Of course, the self-cleaning device may also not comprise a centrifugal receiving assembly 22, i.e. the cleaning chain 20 is always in a free state. In addition, it should be noted that the present invention does not limit the specific structure of the centrifugal accommodating component 22, and the skilled person can set itself according to the actual use requirement, as long as when the driving shaft 15 rotates at a high speed, the centrifugal accommodating component 22 can pull the cleaning chain 20 tightly to make the cleaning chain 20 get out of contact with the bottom of the inner tub 13; for example, the centrifugal accommodation assembly 22 may also be composed of an electromagnet disposed on the bottom surface of the pulsator 14 and a plurality of iron blocks disposed on the cleaning chain 20, and the pulsator washing machine may energize the electromagnet disposed on the bottom surface of the pulsator 14 when the driving shaft 15 is rotated at a high speed, so that the electromagnet may attract the cleaning chain 20 to the bottom surface of the pulsator 14 through the plurality of iron blocks, thereby bringing the cleaning chain 20 out of contact with the bottom of the inner tub 13. In addition, as can be understood by those skilled in the art, the high-speed rotation described in the present embodiment generally refers to a rotation state of the pulsator washing machine when the spin-drying operation is performed, and the non-high-speed rotation described in the present embodiment refers to a rotation state of the pulsator washing machine when an operation other than the spin-drying operation is performed, for example, a washing operation is performed; of course, this is not restrictive, and the skilled person may define the method according to the actual use requirement.
Further, in the present preferred embodiment, the centrifugal housing assembly 22 includes an annular guide groove 222 provided on the pulsator 14 and a centrifugal drawing member 221 provided in the annular guide groove 222; it should be noted that the pulsator 14 generally comprises an upper portion and a lower portion, and the present invention effectively ensures that the cleaning chain 20 can perform a circular motion between the inner tub 13 and the pulsator 14 by providing an annular gap for the movement of the chain body 201 at the connection between the upper portion and the lower portion. Specifically, the centrifugal drawing member 221 is provided in a ball-shaped structure so that the centrifugal drawing member 221 can be more easily moved, and the center of the annular guide groove 222 is located on the rotational axis of the driving shaft 15 so that the centrifugal drawing member 221 can perform a circular motion in the guide groove 222, thereby enabling the cleaning chain 20 to perform a circular motion between the inner tub 13 and the pulsator 14; the centrifugal traction member 221 is connected to the other end of the cleaning chain 20, and the weight of the centrifugal traction member 221 is set to be greater than that of the cleaning chain 20 so that the centrifugal traction member 221 can tighten the cleaning chain 20. It should be noted that, the technician can set the weight of the centrifugal traction member 221 according to the actual use requirement, as long as the centrifugal force generated by the centrifugal traction member 221 is enough to tighten the cleaning chain 20 when the driving shaft 15 rotates at a high speed. As shown in fig. 3, when the driving shaft 15 rotates at a high speed, the centrifugal traction member 221 can move in the guide groove 222 to an end far from the driving shaft 15 by the centrifugal force, and since the weight of the centrifugal traction member 221 is greater than that of the cleaning chain 20, the centrifugal force generated by it can pull the cleaning chain 20 tight, so that the cleaning chain 20 is out of contact with the bottom of the inner tub 13 to achieve the storing effect. Further, as shown in fig. 2, when the driving shaft 15 is not rotated at a high speed, both the centrifugal traction member 221 and the cleaning balls 202 can freely swing within a range restricted by the chain body 201, thereby performing a cleaning function. It should be noted that, the invention does not limit the specific structure and the arrangement position of the centrifugal traction member 221 and the guide groove 222, and the technician can set the configuration according to the actual use requirement as long as the tensioning function can be realized; for example, the centrifugal drawing member 221 may be a square block, and the guide grooves 222 may be a plurality of arc-shaped grooves separately provided and used in cooperation with the plurality of cleaning chains 20. All such changes in the details as come within the meaning and range of equivalency of the claims are to be embraced within their scope.
